Fig. 1From: Role of dynamic ultrasound versus MRI in diagnosis and assessment of shoulder impingement syndromea MRI, coronal T2WIs: acromio-clavicular osteoarthritis and thickening of supraspinatous tendon with increased signal intensity yet no fiber discontinuity. b Static US image showed evidence of acromio-clavicular osteoarthritis. c Static US image showing swollen supraspinatous tendon with ill-defined hypoechogenicity yet with preserved fiber continuity. d Dynamic ultrasonography showed narrowing of the subacromial tunnel in stress positionBack to article page
